NAILING IMPLEMENT.

To all whom it may concern:

Be it known that I, BERNARD R. KABIG- TING, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Nailing Implements; and I- do hereby declare the following to be a fulLjclear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

The invention provides a tool embodying a magazine and nail race and a hammer, whereby the nails are automatically fed into proper position and driven home, the nails being held and guided throughout the driving operation, thereby preventing marring a finished surface by failure to strike the nail when aiming a blow thereat. The blows are also delivered squarely upon the head of the nail, thereby driving the same straight without liability of bending the nail as frequently occurs by reason of the blow being delivered to one side of the center of the head. a

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention, it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring tothe accompanying drawings forming a part of the specification,

Figure 1 is an elevation of a tool embodying the invention,

Figure 2 is a central longitudinal. section thereof,

Figure 3 is a horizontal section on the line 01-w of Figure 2, and

Figure 4 is a modification.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The tool embodies a casing 1 and a cap 2 slidably mounted upon the upperend of the casing. A core 3 is secured within the casing l and has a central longitudinal opening extending therethrough. The'upper portion. of the opening is enlarged, as

indicated at 4, and the lower portion is constricted, as designated at 5. A hammer or plungerfi is slidably mounted in the enlarged portion 4 of the opening and its driving head is reduced, as indicated at 7, to operate in the constricted portion 5 of the opening. The hammer or plunger 6 is connected with the. cap 2 so as to move longitudinally therewith. An expansible helical spring 8 is interposed'between the upper end of the core 3 and the closed end of the cap 2 and normally holds the hammer in withdrawn or driving position. The core 3 is \preferably made in similar longitudinal halves or sections in each of which the opening for the hammeror plunger is partly formed. .Dowels 9 hold the parts or sections of the core in proper position. Suit able fastenings, as screws 10, hold the core and casing in proper position. The driving end of the core 3 is tapered, whereby positioning of the tool is made easy. A nail race 11 is formed in the outer side of the core 3 and extends in a helical or spiral direction.

- The delivery end of the nail race 11 communicates with the constricted portion 5 of the hammer opening to insure delivery of The helical formation of the nail race insures a positive movement of the nails without a too rapid feed and accommodates a great number of nails because of the extent of the race. The upper end of the nail race 11 communicates with an opening 12 formed in a side of the casing 1.- A fiat spring 14 is disposed in the constricted portion 5 of the hammer opening opposite the delivery end of the nail race 11 and engages and supports the nails to prevent their premature discharge from the tool.

In practice, nails 13 are supplied to the nail race 11 through the opening 12 and after the nail race has been filled, the easing 1 is turned upon the core 3 to close the opening 12. When it is required to drive a nail, the tool is positioned with'its point ophammer orplunger in a manner well understood. It will be understood that each blow of the hammer or plunger is delivered squarely upon the head of the nail, thereby obviating any possible injury to a highly rposite the spot where the nail is to be driven. Y

polished surface-such as would be occasioned y the hammer missing the nail or slipping therefrom. directed throughout the driving operation and is prevented from bending or leaning to one side or the other as is the case when driving nails in the usual way and which is objectionable.

In the modification shown in Figure 4, the trap 2 is provided in a side' with an opening 15 to receive a box 16 for holding a quantity of nails in reserve to supply the 113,11 race when the latter has become exhausted or needs replenishing.

What is claimed is: i i p 1. A tool'of the character specified comprising a casing a core within the casing and having a longitudinal opening and a helical nail race, a cap slidable on the eas- Moreover, the nail is held and V ture in presence of two witnesses.
